Injection ports were installed at 1’ on center spacing to allow for the SealBoss Hydrophobic Water Stop Foam Material to penetrate the joint and create the seal between the Stainless Steel and Concrete Pool. The Hydrophobic Injection Foam created a chemical reaction with a damp wet surface to create the catalyzing process and foam reaction to create the seal. Seal boss has a wide variety of products that can be installed in all circumstances. SealBoss can even be installed under active pressurized leaking conditions.
